This reservoir has a middle baffle (blue) that helps it keep its shape. Unfortunately, the baffle also makes it impossible to turn the reservoir completely inside out for for cleaning/drying. This seems to be a design flaw that was corrected in later models, where the baffle can be zipped open and shut, like a ziploc bag. But not this one. Otherwise, the product seems sturdy.

It has taken several changes of water to start tasting less like plastic, but what would you expect? The quick release hose, the bite valve, the filler clip, everything works better than I had though it would. I took it recently on a motorcycle camping trip and it was great. No leaks in the tank bag.
